Modern Architectural Structures 3D Renderings

I'm in need of two 3D rendering images depicting modern architectural structures. The level of detail required is basic, with simple shapes and without intricate textures.

Ideal candidates for this project should have:
- Proficiency in 3D modeling software
- Prior experience with architectural visualizations
- Ability to create visually appealing basic level designs

Please, include similar past projects in your portfolio for consideration.
